Using Code Folding

Code Folding collapses or "folds" the display of a block of code.

To enable code folding, go to the Folding Preferences page, accessible from Window | Preferences | PHP | Editor | Using Code Folding .

If Code Folding is enabled, minus signs will appear in the Annotation Bar next to code blocks which can be folded. In addition, certain elements will be folded by default according to the Folding Preferences settings.



Instructions on how to complete a procedure

To fold a block of code:

  1. Stand within a class, function or PHPDocBlock.

  2. Click the minus sign on the marker bar to the left of the editor.

The first line of code will remain visible but the other lines will not be displayed. A fold indicator code_folding_indicator.pngwill appear at the end of the line when the code is folded to indicate that there is hidden code.

To temporarily view folded code, hover over the plus sign that denotes a folded block. The folded code will be displayed in a floating block.

To fold/unfold nested functions:

  1. Click on one of the minus signs of a nested function. All levels below this level will be folded into it. You can continue to fold until all levels have been folded into the topmost level.

  2. To unfold nested functions, click on the plus sign. The folded code will open in the same order that it was folded.



Line numbers are folded together with the code. Folding and unfolding does not change line numbers, it can only hide/display them.


If the folded code contains an error, the displayed window will be syntax highlighted on both the left and right Annotation bars.
